Method of Testing Seed.—If the plumule and radicle of the embr}'o are carefully exposed by means of a sharp knife, these parts will be white and plump. Any discoloration or wilting is evidence of injured vitality. To determine vitality definitely, seed should always be tested before using. This may be done by any method which furnishes proper condi- tions of heat, moisture and air. A satisfactory method is to fill any receptacle similar in size and shape to a dinner plate with sand. Pour on water until it covers the surface of the sand. Gently drain off water. Place grains in the moist sand, thoroughly covering them, and cover receptacle by inverting a simi- lar one over it to prevent too rapid evaporation and place in a tempera- ture of 80° F. If ninet\'-five per cent of the seed fails to germinate in five days, the seed is unsatisfac- tory.

In some cases it may be desirable to test each ear separately by taking ten grains from each ear. In no case should an ear be used in which nine out of the ten grains failed to germinate under conditions Please note that these images are extracted from scanned page images that may have been digitally enhanced
